Inside the World's Largest Science Experiment

Dianna from Physics Girl visited CERN in Geneva Switzerland to find out what the detectors at the LHC are looking for, and dive into the fundamental question: what are particles?

I never asked those questions as a kid. I was more concerned with finding brown cows so I could see where chocolate milk came from.

Looks like they were very conCERNed about security.

Big love out to Physics Girl!! May you heal fully and be back doing what you love inspiring us.

The wonder and excitement in Dianna's voice over science is contagious.

Thinking about the Severed Body Parts Kit, makes me wonder how many times did it to take to occur that they made a Kit for it?

[silvanodegennaro]

Very cool. Congrats Dianna 👏. And that comes from CERN's former video producer. I spent two decades producing exactly this kind of clips, which are still on the CERN YT site, but none of them is as cool and clear as this. Hope it motivates kids to join the quest, which is really fascinating.

So we aren't stardust, we're Higgs poop.

I see a lot of comments wondering about why we use the elevators instead of stairs in-case of emergencies. Reason is that the experiments are 100m underground, and climbing the stairs up for 100m is demanding even for a fit person. Therefore the lifts (and lift entrances) are positively pressurized and powered by a separated power system with multiple backups to ensure function and safety even in the most extreme emergencies. Also the lifts are specially made for CERN and ensured to function even under strong magnetic fields that are present when the detectors are "switched on".

Ps. Great video :)

The earth map is a perfect quantum field analogy! You can determine which "particle" should be located where. If you visit that place, you are most likely to find that said particle.

I love that you gave Dr. Delannoy the floor and just let him speak about his topic. There are so many Youtubers out there that will interview people but interrupt them, and other impolite things. Like, we just want to hear the expert talk!

The more you learn, the greater what you don't know gets.

Miss Physics Girl, You explain this so well! Soooo much better than the rest of the videos "out there." But I've come to expect that from you, because you do it time and time again. You are my "goto" when I want to get an understanding of fundamentals of physics. Thank you!

"The quantum field exists even if there is no particle in it, just like how an ocean can exist even if there is no wave in it" -- Beautiful!
Quantum field theory makes particle-wave duality feel so intuitive. I hope there will come a day where high school STEM teachers stop drawing little orbiting balls. I think for a lot of children QFT is actually easier to understand (the concept, not the math). Quantum mechanics sounds very scary, but I think the elegance of it makes it easier to understand than all these outdated analogies, even for young children.

“Higgs Boson -It's like you blend in a bunch of fruits in a smoothie and popped out a *chicken Nugget* ” lmao best line

I love the musical instrument analogy that was used. because it happens, and for no apparent reason. With the volume so low that there should be no shared resonance, if you mic up a guitar in the same vicinity, it will begin to resonate. My friends called it proof of magic, I called it the interconnectedness of all things. Much like the "Long Dark Tea Time of the Soul". My understanding is that this is why you can know how a friend is feeling, even when they are miles away. It's not magic, it's just fact that most of us don't understand yet! (I love your work Physics Girl Dianna!)

[TheScienceBiome]

Jeez one can only imagine the amount of engineering it took to build that monstrosity. I’m in awe.

Great job!Thank you so much for making this video. I subscribed a long time ago and your videos have gone from pretty cool to very interesting to high quality and on par with Mythbusters and I think the next level for you is documentary quality. Congratulations on your success on YouTube and thank you for creating and sharing the content with us. Stay cool and nerdy.

The way this guy says poop is wierdly soothing.
